Subject: [PATCH 5.9 470/757] RDMA/mlx5: Fix type warning of sizeof in __mlx5_ib_alloc_counters()

From: Liu Shixin <liushixin2@...wei.com>

[ Upstream commit b942fc0319a72b83146b79619eb578e989062911 ]

sizeof() when applied to a pointer typed expression should give the size
of the pointed data, even if the data is a pointer.

Fixes: e1f24a79f424 ("IB/mlx5: Support congestion related counters")
